You can't simply convert something into a vector form, you need to remake this manually in Photoshop.

Yes You can. Most vector editors have bitmap to vector tracing option.

Here are the traces, I have the vector files if You are interested to use them. Vectors can't be uploaded to an image host so what You see here are png exports of the vector files.I have them all in .svg, .ai, .pdf and .eps format.Note, I used very basic settings to trace these. If I put settings higher, there will be enormous amount of paths and it'll take long time to trace.But the paths are easy to edit because all segments of all single colors are grouped into 1 object. You can easily manipulate them.

Scaled x2 and removed the text from left down corner.

Here's the second image, again used 6 colors. I will trace it again shortly, it takes much more time than the first because it's bigger and has lot more content.

Same in 10 colors

3rd image, 10 colors trace. You can see how the english text is little messed. But they are just segments and can be easily removed in vector editor.

It looks very good. Thanks!

Can you upload them to rapidshare maybe in a rar package? Actually the first picture would be enough, since I want to let it print as a poster. So I need it in a good quality, when it is scaled up. Is it possible to add a mosaic effect (and maybe for all parts except the black areas)? At least I couldn't find that option in Inkscape.

So basically I need the first picture as a high quality vector graphic with and without a mosaic effect.

Sure, here You have the face image.Inside the zip archive You have the image1.) Without black background. That's if You want to manipulate the face yourself and put black or something else in the background afterwards.2.) With black backround.3.) Mosaic face with black background.

All these are scaled 800% before exporting. That should be big enough for poster.

Also in archive are without background and with background vector versions in .svg, .eps, .ai and .eps format.You can open the svg files in inkscape and play with them if You know how to.

As for the mosaik effect. Is there a freeware program that can add another mosaic effect. I thought of something different, I want many small and edgy tiles. But the edges between the different colour areas should stay the same.

You mean like the colored church windows? Then itīs not Mosaic, itīs called Stained Class.There is a stained class filter in Photoshop, should be in some free editors too.If You donīt get the wished result by yourself I can do it later, donīt have time right now.
